My hosting provider told me I can install Discourse but the Redis is shared and that I “must not put in Redis sensible informations” I would like to know **what kind of information is stored in Redis (the list)** with Discourse so I can decide whether or not I can install it. I cannot read the whole source code I am not a developper I don’t posess the And especially if emails or identity of the users of my forum would be endangered. #security ![](https://media.tenor.com/videos/70282aeb46abf7d7b5f741da91350d0e/mp4) ---

Discourse does store some sensitive data in Redis. You shouldn’t share the Redis instance with another application. We strongly recommend you follow our official installation guide, which will automatically include a dedicated redis instance: [discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub](https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md)
